Abstract: There is provided a method for network management performed by a first entity (10), which is configured to manage network slices in a network. The method is performed in response to a first request to set up a first network slice. The method comprises identifying (102) one or more network nodes in the network and/or one or more second network slices to support the first network slice. For each identified network node, an update to an attribute of the identified network node is initiated (104) to add a unique identifier of the first network slice to the attribute of the identified network node. For each identified second network slice, an update to an attribute of the identified second network slice is initiated (106) to add the unique identifier of the first network slice to the attribute of the identified second network slice.

Abstract: In a network Fault Management (FM) model, network equipment (160) maintains a ManagedElement object (12). The ManagedElement object contains one or more ManagedFunction objects (14, 22, 24, 26) with each ManagedFunction object (16) comprising an FMControl object specifying the capabilities of the ManagedFunction objects to produce, report, and log fault reports, a Fault Type List object (18) listing the various types of faults the ManagedFunction object can detect, report, and log, and a currentFaultList object (20) listing the current faults and associated fault information. The FMControl object further includes several attributes that are set by a Management System (30) to control the reading of fault reports as well as the sending of the fault reports to other interested network nodes (190).

Abstract: Aerial vehicles are assigned to routes within a transportation network based on a state of charge, state of power, and/or state of health for the aerial vehicle. Such aspects can be modeled based on one or more statistical models and/or machine-learned models, among other examples. As another example, an energy budget is used to ensure that the state of charge, state of power, and/or state of health of the aerial vehicle during and/or after traveling the route remains within the energy budget. A payload is assigned to a route and an associated aerial vehicle, thereby generating an itinerary. In examples, the itinerary is validated by the aerial vehicle to ensure that the aerial vehicle is capable of traveling the route with the payload. In examples where the aerial vehicle rejects the itinerary, the itinerary is assigned to another aerial vehicle and a new itinerary is identified for the aerial vehicle.

Abstract: Described herein are examples of a computerized method that comprises: in response to obtaining information regarding a potential collision between a vehicle and an object, obtaining data describing the vehicle for a time period extending before and after a time of the potential collision. The method may determine a likelihood that the potential collision is a non-collision event based on the data describing the vehicle by performing one or more assessments. The assessments may include telematics monitor assessment, driver behavior assessment, road surface feature assessment, trip correlation assessment, and/or context assessment. In response to determining that the likelihood indicates that the potential collision is not a non-collision event, the method may trigger one or more actions responding to the potential collision.

Abstract: Embodiments include methods for a first radio network node (RNN) in a wireless network to configure quality of experience (QoE) measurements by user equipment (UEs). Such methods include receiving, from a measurement function in the wireless network, a QoE measurement configuration (QMC associated with one or more service types; and configuring one or more UEs with the QMC. Such methods also include sending to a second RNN in the wireless network, a first request for handover of a particular one of the UEs from a first cell served by the first RNN via a first radio access technology (RAT) to a second cell served by the second RNN via a second RAT. The first request includes the QMC. Other embodiments include complementary methods performed by a second RNN or by a UE, as well as first RNNs, second RNNs, and UEs configured to perform such methods.

Abstract: A method of operating a UE to provide feedback on a streaming session. The method includes determining when a streaming session used by an application layer of the UE is being started and/or ended. Responsive to the determination, the method transmits an indication to a RAN that the streaming session is being started and/or ended. A corresponding method of operating a network node is provided to control reporting relating to streaming sessions of UEs. The method by the network node receives an indication from an UE that a streaming session is being started and/or ended, and controls whether a Quality of Experience (QoE) configuration file is sent to the UE responsive to the indication.

After transitioning from the idle or inactive state to a connected state and after handover from a source cell associated with the first RAT to a target cell associated with a second RAT, the wireless device transmits (1206) at least one MDT report to a target network node associated with the target cell.

Abstract: For ultrasound imaging using a matrix transducer, interconnects or switches are provided to allow sub-arrays forming a 1D array, such as with sub-arrays one element wide with the maximum number of elements in elevation. Where groups are used to limit the switches and available system channels per group, an extra switch may connect between elements of different groups through a group output to extend a sub-array across groups. To further limit the number of switches, the group may be sub-divided where different combinations of sub-groups are connectable with different combinations of the system channels for the group.

Abstract: In a network Performance Measurement (PM) model, network equipment (10) maintains (102) a ManagedElement object. The ManagedElement object contains one or more ManagedFunction objects which perform and report measurements. Each ManagedFunction object has one or more Measurement objects (106) that specifies a measurement, and lists a reporting period. The ManagedElement object contains a PMControl object (104), which specifies the reporting mode and includes an administrative state attribute of the ManagedElement object that is controlled by the network management system (20). The ManagedElement object controls (110) an operational state attribute of the PMControl object based on resources to perform the measurement and access to the relevant reporting mechanism (108). When both states of the PMControl object are set to a functional value (112), the ManagedFunction objects perform (114) and report (118) the results of measurement specified in associated Measurement objects.

Abstract: Methods and apparatus for correlating event notifications between agents in a management network are provided. An agent constructs a network notification in response to receiving an event notification. If the received event notification is associated with a prior notification already received and stored by the agent, a correlation attribute is added to the constructed network notification. If the received notification matches a peer agent notification category that another agent in the management network is interested in receiving, the constructed network notification is sent to the other agent.
